Application November 13, 1951, Serial No. 255,913

2 Claims. (Cl. 222-498) The present invention relates to a closure andit particularly relates to a combination snap-top, screwtype closureparticularly applicable to bottles.'

Although the present invention has abroad application to screw-top,snap-type closures of the combination type, it has a specificapplication to closures for cosmetic, pharmaceutical and liquidcondiment containers where it is desired to have the closure readilyremovable as by a screw or bayonet connection to permit re-iilling ofthe bottle, and where it is also possible, by a simple manipulation,which does not remove the cap from the bottle, to permit dispensing ofsmall quantities of liquid from the bottle in connection with cosmetics,pharmaceuticals, ilavoring materials, perfumes, liquid dressing and thelike. y It is among the objects of the present invention to provide asimple, inexpensive, durable, readily manufactured screw-cap forcosmetic containers or the like, which may be readily applied to sealthe cosmetic container and ing the cap or closure.

Still further objects and advantages will appear in the more detaileddescription set forth below, it being understood, however, that thismore detailed description is 'I giveny byway of illustration andexplanation only and not by way of limitation, since various changestherein may be made by those skilled in the art without departing fromthe scope and spirit of the present invention.

In accomplishing the above objects, it has been found most satisfactory,according to one embodiment of the present invention,'to provide aplastic type screw cap which may be readily applied and removed from thebottle by means of a bayonet or screw-type connection.

The upper portion of the container desirably has a swinging hingeconnection member which has a snap connection to a simple opening orspout through the top of the screw cap.

This central opening is of such a shape and size that small quantitiesof the liquid, whether it be a cosmetic, pharmaceutical, dressing orliquid material, may be dispensed by inverting the bottle, removing thescrew cap and reciprocating the same.

Desirably, the bottle has a sealing means which will seal the spout oropening of the spout upon complete closure of the cap.

The spout is desirably so arranged that it may snap into a recess in thehinged, upper portion of the screwtype closure to assure completesealing.

With the foregoing and other objects in view, the inice vention consistsof the novel construction, combination and arrangement of parts ashereinafter more specifically described, and illustrated in theaccompanying drawings, wherein is shown an embodiment of the invention,but it is to be understood that changes, variations and modificationscan be resorted to which fall within the scope of the claims hereuntoappended.

In the drawings wherein like reference characters denote correspondingparts throughout the several views:

Fig. 1 isa side perspective view of a bottle or container which may beutilized according to a preferred embodiment of the present invention,showing the main body 'of the cap screw or otherwise connected to thebottle opening with the cover element removed from the top of the screwcap.

Fig. 2 is a transverse vertical sectional view upon the line 2-2 of Fig.l, upon a large scale as compared to Fig. l.

Fig. 3 is a side sectional view of the closure of Fig. 2, as applied toa bottle, showing the upper cap portion in closed position.

Fig. 4 is a side sectional view similar to Fig. 3 of an alternateembodiment of the present invention showing a different form of springretainer for the spout nipple member.

Fig. 5 is a transverse sectional view upon the line 5 5 of Fig. 4.

Referring to Figs. l, 2 and 3, there is shown a bottle A which may be ofglass or a pliable, plastic material,

having a screw cap B with a removable snap cover C.

Referring particularly to Figs. 2 and 3, there is shown a neck 10 forthe bottle A with a screw formation 11 on the outside thereof.

This neck 10 is designed to receive the sleeve 12, which may be of amolded, plastic material having an interiorly threaded portion 13.

The outside of the sleeve has the depending apron 14. The lower edge 15of the apron 14 should terminate a short distance above the top contour16 of the bottle A.

Desirably, the sleeve 12 has a top, transverse plate member 15 molded`integrally therewith and there is inserted against the plate anintermediate element 16.

The intermediate element 16 supports the washer 17, which forms a tightcontact with the top face 18 of the screw neck 10.

The screw neck 10 will be jammed against the periphery of the washer 17to assure a seal.

The element 16 is recessed, as indicated at 25, to form ber 27.

The nipple member extends upward and mushrooms as indicated at 28, whereit is received inside of the spheroidal head 29 of the male snap member30. The male snap member 30 has an outstanding flange 31 which isattached to the base 32 of the recess 33 in the top of the cap B.

It will be noted that the washer 17, the intermediate element 16, thenipple 27 and the spheroidal head 30 have the through-passages 34, 35,36 and 37, through which the liquid in the container A may be spurtedupon inversion and reciprocation thereof.

Extending outwardly from one side of the sleeve 12 is the hinge member45, which has an eye at 46 receiving the pivot pin 47.

The pivot pin 47 extends through the eye 46 and into the clevis jawmembers 48 depending from and attached to the snap top C.

The snap top C consists of a molded plate 55 having the projectingforward portions 56, which serve as a finger or hand-manipulatingmember.

The recess 57 receives a supporting inset plate 58 which holds thefemale snap member 59 in position.

.t3 Thefemale snap member is received in a recess 60 fand-it has aSpheroidal recess member 61. The spheroidal recess member 61 receivesthe spherical cap or i, spherical,Ahead.:3(1,attachedjo.,theloyvecsereigkcap;,B
